Returns the field's list of values as a single String.
This method returns a single String. If a field contains a list of values, the String contains a concatenation of the values, separated by newline characters. For a field that returns multiple values, you can use the GetValueAsList method to get a separate String for each value.
To determine if a field can contain multiple values, call the GetType method on the corresponding FieldInfo object. If the type of the field is REFERENCE_LIST, ATTACHMENT_LIST, or JOURNAL, the field can contain multiple values.
Fields whose type is either ATTACHMENT_LIST or JOURNAL cannot be modified programmatically.
